The invention relates to the field of automatic driving, in particular to a simulation traffic scene file generation method and device. The method comprises the following steps: acquiring road test data, wherein the road test data comprises traffic scene data acquired when an automatic driving vehicle performs a driving test on a real road; determining a first moment when the automatic driving vehicle enters a first driving state or generates a request for entering the first driving state during the driving test; determining first segment data from the road test data according to the first moment and the own vehicle information of the automatic driving vehicle in the driving test period; and generating a description file of the simulation traffic scene at least according to the first segment data. According to the method, the data of the key traffic scene can be automatically extracted from the road test data, and the description file for describing the simulation traffic scene is generated, so that the method can be used for reproducing the key traffic scene, and the authenticity, completeness and sufficiency of the scene can be tested or verified by an automatic driving algorithm.
本申请涉及自动驾驶领域,尤其涉及一种仿真交通场景文件生成方法及装置。所述方法包括:获取路测数据,路测数据包括自动驾驶车辆在真实道路上进行行驶测试时所采集的交通场景数据;确定自动驾驶车辆在所述行驶测试期间进入第一驾驶状态或产生进入第一驾驶状态请求的第一时刻;根据第一时刻和所述自动驾驶车辆在行驶测试期间的自车信息,从路测数据中确定第一片段数据;至少根据第一片段数据,生成仿真交通场景的描述文件。该方法可以自动从路测数据中提取关键交通场景的数据,并生成用于描述仿真交通场景的描述文件,从而可以用于复现关键交通场景,进而可以保证自动驾驶算法测试或验证场景真实性、完备性以及充分性。
